GEo. i. BYRD ANDIPETERMILHNE, or NEw YORK, N. Y.

BATHING APPARATUS.

Specification of Letters Patent No. 1,636, dated February 8, 1840.

To all whom t may concern.'

Be itknown that we, GEORGE I. BYRD and PETER MILNE, of the city and county of Newl York and State of New York, have invented a new and Improved Mode of Constructing I-Iot and Cold Water Bathing Apparatus; and we do hereby declare that the following is a full and eXact description thereof.

The nature of our invention consists in providing the bathing tub with a compound standing pipe as shown in the drawings, the said standing pipe being so arranged as to admit hot and cold water through 'one aperture into the bottom of the bathing tub and also to convey the waste water off through the same aperture, so that there is but one opening in the bathing tub whereby the hot and cold water enters and by which the waste water escapes, and there is also combined with this said standing pipe an overflow pipe which in every instance will prevent the bathing tub from overflowing even supposing the hot and cold water valves were left open by accident.

We construct our bathing apparatus as per drawings or in any other way or form best suiting the situation. We usually place the bathing tub (which is made in the ordinary way) in the second story of houses and a copper boiler in the kitchen. We provide a reservoir to hold a sufficient quantity of water and place it directly over the bath ing tub, elevating it about 6 or 7 feet above said bathing tub. This reservoir is marked B in the drawings. In the bottom of this reservoir there are two valves opening upward, one for hot and the other for cold water. Said valves are opened and shut by means of the handles or cranks marked K (with copper wire connecting the same) in sectional drawings. The lead pipe D extends from said reservoir down to the boiler of water in kitchen and coiled in said boiler about 100 feet andreturnedto andisbranched into the compound standing pipe or to that branch of it leading to the aperture G, as shown in the drawings. The valve on the upper end of pipe D, at the bottom of reservoir B, when opened lets the water into said pipe and passes through the coil E in boiler and returns to the bath hot through the pipe F, entering -at the aperture G. The pipe D,

with the coil E, and the ascending pipe F, being one and the same pipe continued andit being an ascertained fact that water will kalways find its own level so in this case the reservoir before described stands 6 or 8 feet above thebathing tub and consequently when the water is let into the pipe it mustV rise and flow into the bat-hing tub. Again the pipe M, leading from the other valve in the aforesaid reservoir extends from the same directly to the compound standing pipe connecting with the same or to that branch of it leading to the aperture G, as before described. This pipe supplies cold water to the bath. This pipe will be seen in the model and if- I mistake not in the drawings also. Again we place the waste water valve J, in the aforesaid compound standing pipe between the branch of the same which leads to t-he aperture G, and the lower branch of the overflow pipe I. This valve also opens upward. The situation of this valve will also be seen by reference to the model or drawings. This valve is also opened and shut by means of one of the cranks or handles marked K in the same manner as the hot and cold water valves,

so that we have three lever cranks or han# dles engraved on one Hot-, on another Cold and on the third Waste and placed parallel to each other in a convenient manner to be worked, there being also a point indicating open and shut engraved on the same.

compound standing pipe 'as a general rule we make its caliber about six times larger than the hot and cold water pipes which are branched into it, consequently cannot overflow even supposing both pipes being let run at the same time. The bathing tubs are generally about 22 inches deep and we place our compound standing pipe at the foot the overflow of the same extending to within 4 inches of the top; but it is never intended to lill the bath to that height before getting into it. About-fourteen inches of water'is always sufficient ina bath for This lwill leave eight inches-space in the bath for the water to rise according to the specific gravity of the person bathing.
